About this map

The South Pine Oil Field dominates this 1981 landscape at the intersection of Prairie, Wibaux, and Fallon Counties. This portion of eastern Montana reflects an era of intense resource extraction, characterized by a dense network of an Oil Well, Pumping Sta, and a central Pine Unit and Gas Plant. A prominent Pipeline cuts across the northern terrain, linking these industrial sites to broader markets.

Beyond the oil infrastructure, the map reveals a sparsely settled region defined by its watercourses, including Cedar Creek, Horse Creek, and Cabin Creek. The small settlement of Cabin appears in the west, while the land is further segmented by the surveyor's lines for Prairie, Wibaux, and Fallon county boundaries. The presence of a Gravel Pit and numerous Drill Hole sites underscores the heavy industrial activity that transformed this rural frontier.
